Powdery Mildew - Kulowetsa Bowa
M'malo mwake, powdery mildew ndi matenda oyamba ndi fungus omwe amafalikira (kenako amakula mwachangu) osati mu mphepo kapena tizilombo, komanso fungus tating'ono tomwe tili pansi pa mapazi anu m'nthaka. Amakhala amtundu wovuta, koma, kwenikweni, dongosolo losavuta kwambiri la powdery mildew, kapena erysiphous.
Monga tanena kale, ufa wa powdery ndi "wopatsa", umatha kudya zipatso zomwe mumakonda, maluwa okongola, zipatso zam'madzi (chifukwa malo ake ndi ochepa), pafupifupi mbewu zilizonse, mapichesi, komanso nkhaka, squash ndi maungu ndi masamba ena azomera.
Zizindikiro ndi zotsatira za powdery mildew
Chizindikiro choyambirira chomwe muyenera kuyang'anitsitsa ndi, mwachitsanzo, kuphimba kwa ufa, ndipo nthawi zina zimachitika kuchokera pansi pa tsamba (iyi ndi downy mildew) komanso kuchokera pamwamba (zenizeni). Ndipo ngati anawo sanayende mozungulira pamalowo, kufalitsa china chakecho pamalowo, ndipo pambali pake, mabowo anali atakhuthala, nthaka sinali yoyambira yatsopano, ndipo mvula inali kugwa nthawi zambiri kuposa momwe timafunira, ndiye kuti panali lingaliro limodzi - tsoka ili, mwatsoka, silinathawe . Nthawi zina pamiyala yoyera, milu yonyowa yowoneka bwino imatha kuoneka, koma chikhomo chingakhale popanda iwo.
Nthawi zambiri pazomera zamasamba, ufa wa powdery umangowonekera osati masamba okha, amathanso kukhala pa petioles, komanso pa mphukira zazing'ono, komanso zipatso ndi mapesi. Kachilombo koyambirira kamalowa kudzera m'masamba, ndipo tsamba limayandikiririka pansi. Zomwezi zimagwiranso ntchito pakuwombera kwa chomera chamasamba - chimakankhidwa pansi, zomwe zikutanthauza kuti kuthekera kuti kachilomboka kachikwaniritsidwa. Ndipo kenako chilichonse ndichosavuta - matendawa amatenga chomera chonse chokwanira.
Ngati ndinu amisala mwachilengedwe, ndiye kuti mutha, mutakhala ndi galasi lokulitsa, yang'anani bwino malo omwe mycelium amalumikizana ndi tsamba ndi zilonda zopezeka m'malo ano. Zikuwonekeratu kuti chomera chikuyamba kufota, chifukwa mafangayi amakoka chakudya ndi chinyezi zambiri, ndipo masamba omwe ali pansi pa bowa sangathe kuchita bwino.
Zomera zamasamba zochepetsera zachepetsa mphamvu yakuuma kwa dzinja ndi kukana zoyipa paz chilengedwe. Pakadali pano, ming'alu yayikulu nthawi zina imakhazikika pazipatso zamasamba omwe zipatso zimalowa, zowola zimayamba, zowola zimayamba kugwira ntchito, ndipo zimangokhala zosatheka.
Kodi ufa wofinya kwambiri umagwira ntchito liti?
Powdery mildew imagwira ntchito kwambiri pazomera zamasamba muzaka zambiri zonyowa (65-75%), yotsatana ndi kusinthasintha kwa kutentha kuchokera +14 mpaka + 26 ° С. Powdery mildew yazomera zamasamba imayendetsedwa ndikusinthasintha pafupipafupi kutentha kwamasana ndi usiku, komanso chifukwa cha zolakwika zomwe zimachitika, mwachitsanzo, ndikukhomekera molakwika kwa phwetekere pomwe hemp (mbali za stepson) kapena masamba omwe amakhala kumapeto kwenikweni kwa mbewu atatsala.
Kuphatikiza apo, ufa wa powdery nthawi zambiri amawukira masamba, ngati wokonza dimba atapanga zochuluka kwambiri za feteleza wa nayitrogeni, izi zimachepetsa chitetezo chokwanira cha mbewu, ndipo ufa wa powdery uli pomwepo. Mwachilengedwe, simuyenera kupulumutsa malo ndi kubzala mbewu zambiri pamalo omwewo, kuyesa kubzala mbewu yayikulu, kubzala kuyenera kuyang'aniridwa moyenera, mwina sichinyowa chitha kuzimiririka kuchokera panthaka, ndikupanga malo abwino opangira mbewu za masamba.
Nthawi zambiri, kupsinjika kwa kubzala kumatsimikiziranso kayendetsedwe ka kayendetsedwe - wolimayo amaganiza kuti popeza adabzala mundawo mwamphamvu kuti palibe malo omasuka, ndiye kuti mbewu zikukumana ndi chinyengo champhamvu kwambiri ndipo zimafunikira thandizo. Amatenga payipi ndikusintha chilichonse kukhala chithaphwi, potero amapanga zofunikira kuti ziwonekere ngati Powawa.
Kuphwanya lamulo la ulimi wothirira ndi chifukwa chinanso chakuonekera kwa mtundu wa Powdery m'munda. Nthawi zambiri ku dacha, kuwonekera kamodzi kumapeto kwa sabata, ifenso timathirira mbewu zathu zamasamba ambiri, kenako kuiwala zaiwo, kutsegula zipata ndikulola phokoso la ufa m'deralo.

Kuteteza kwa Powdery Mildew
Mwachilengedwe, ufa wa powdery ukhoza kumenyedwa, koma kupewa ndikofunikira kwambiri, ndipo simuyenera kugwiritsa ntchito chemistry poyambira zizindikiro zamatendawa muzomera zamasamba.
Njira zodzitetezera ndizofunikira komanso zothandiza. Mwachitsanzo, muyenera kuthirira mbewu pokhapokha dothi lapamwamba litapukutiratu, ndipo ngati mvula idavunda ndipo dothi lonyowa, ndiye kuti simuyenera kuyiphatikiranso, chifukwa izi si mbewu zamitengo, ndipo mizu yake siyili kutali kwambiri ndi nthaka.
Muyeso wachiwiri - ndikofunikira kuyang'anira kasinthasintha wa mbewu, ndikuchotsa zinyalala zonse za mbewu pamalowo mutangokolola zonsezo. Njira ina yofunika yodzitetezera ndi kulima ufa wa mitundu ina yosakanizidwa ndi mitundu ina ya masamba. Ndipo - osagwiritsa ntchito feteleza wa nayitrogeni, makamaka munthawi ya kuphukira.
Mwa njira, za feteleza: tikuchenjezani kuti musayike feteleza wa nayitrogeni, tikukukumbutsani kuti muthe kugwiritsa ntchito potashi (8-10 magalamu pa sikweya mita) ndi feteleza wa phosphorous (magalamu 7-9 pa mita imodzi) kuti muzitha kudyetsa mbewuyo ndikuwonjezera chitetezo chokwanira.
Nthaka mutakolola zatsalira pofunikirabe chithandizo cha fungicides, kutsatira mosamalitsa malangizo ophatikizidwa ndikungokhala ndi mankhwalawo omwe amaloledwa. Nthawi imodzi, panjira, mwina sikungakhale kokwanira kuthetseratu matendawa kwathunthu komanso kwathunthu, ndibwino kuchitira chithandizo katatu, kapena anayi.
Maupangiri Amodzi a Powder Mildew
Chifukwa chake, tidazindikira kuti ufa wa powdery ndi vuto losasangalatsa kwambiri, ndipo ngakhale titatenga njira zonse zopewera, zitha kuonekerabe pamasamba azamasamba ndipo, chabwino, zimatibera gawo la mbewu (kapena mwina zonse). Chifukwa chake, tiyeni tiwone momwe tingachotsere kachilomboka pamalowo ndipo tisalolerenso.
Ngati simuli wokonda kwambiri umagwirira ndipo mwawona kuti timapepala ta masamba tapeza zokutira zotsekemera, ndiye kuti, mosamala momwe mungathere, kunyowetsa lumo m'mowa nthawi iliyonse ndikusisita zigawo ndi phulusa la nkhuni, chotsani masamba onse azakudya zamasamba pamalowo ndikuwotcha kunja.
Chepetsani kuchuluka kwa madzi othirira, ndikuyenera, tumitsani dothi tsiku lililonse ndikuchotsa udzu woipa pamalowo. Chilichonse ndichopepuka apa: mukamachotsa masamba omwe akhudzidwa ndi ufa wa ufa, mumachepetsa kwambiri mwayi wokhala ndi matenda obwera chifukwa cha mbewu kapena masamba azipafupi.
Zitatha izi, ndikulimbikitsidwa kuti muzitha kuthira mbewu ndi fungicide, titero kunena, kuphatikiza zotsatira. Chofunikira pano ndikugwiritsa ntchito fungola yovomerezeka, yatsopano, kutsatira mosamala malangizo omwe ali paphukusi, monga lamulo, nthawi yoyendetsera chikhalidwe chilichonse komanso mulingo wofanana. Mukamayamwa ndi fangayi, yesani kunyowetsa ziwalo zonse zakudyera masamba - mbali zake zapamwamba komanso zotsika, kuti fungidwe lipangitse zonse zomwe zingatheke, ndipo palibe ngodya zopatsirana.
Powdery Mildew Chithandizo cha Masamba
Powdery mildew pam nkhaka
Sizokayikitsa kuti zitheka kufotokozera chitetezo chodzitchinjiriza mu ufa wazomera zonse zamasamba popanda kupezeka m'nkhani imodzi, buku lonse likufunika pano. Tilankhule za momwe angatetezere ufa wa ndiwo zamasamba akuluakulu, zomwe, monga lamulo, zili patsamba lililonse.
Ngati ufa wa pefy ukapezeka pamasamba a masamba a nkhaka, choyambirira, siyani kuthirira, ndiye muchotse timapepala tonse ta matenda, yesani kupewetsa mbewuzo. Mwachitsanzo, ngati aliyense wa iwo akhudzidwa kwambiri, ndibwino kuti musamachiritse, koma ndikuchotsa pamalowo.
Kenako, onetsetsani kuti akumasulira dothi kuti lithandizire kutuluka kwambiri, ndipo mutha kuyamba kulandira chithandizo. Amadziwika kuti zotsatira zabwino zimapezeka ndikuletsa kufalikira kwa tsamba la nkhaka lomwe limakhudzidwa ndi ufa wa sulufule. Kuti mukonzekere, muyenera kutenga 28-29 g ya sulfure, kuipukuta mu ndowa, kudzaza ndi botolo lothira ndikuyesera kukonza masamba onse ndi dothi pansi pawo.
Yankho la sulufule ya colloidal imathandizanso, imafunanso kuchuluka komweko kwa voliyumu yomweyo, pokhapokha poyambira ngati mungathe kutsanulira mbewu za 5-7 za matenda odwala motere, ndiye kwachiwiri - zonse khumi. Mankhwalawa amachitidwa bwino madzulo. Olima ena alimi amatenga bwino chithandizo cha nkhaka zomwe zimakhudzidwa ndi 10 makilogalamu wovinikidwa, kuchuluka kwake ndikokwanira masentimita 10 mabedi.
Ngati mukuganiza kugwiritsa ntchito fungicides, ndiye kuti gwiritsani ntchito malangizo omwe ali phukusi (mawu, Mlingo, dziwani zonse). Dziwani ngati mankhwala ena aloledwa. M'mbuyomu, kukonzekera kokhala ndi mkuwa ngati "Oxychoma" kunathandizira kuthana ndi powdery mildew, tsopano alemba kuti palibe nzeru kuchokera kwa iwo, mutha kugwiritsa ntchito fungoti "Topaz".
Powdery mildew pa tsamba la nkhaka.
Powdery mildew pa tomato
Ndizosangalatsa kuti ufa wa phwetekere pa tomato amatha kupezeka m'njira ziwiri zosiyanasiyana, makamaka, zimakhudza mbewu zomwe zimakhala ndi mitundu iwiri ya bowa. Mitundu yoyamba ndi Oidiopsiserysiphoides - makamaka m'malo otseguka, ndiye kuti, osati m'malo obisalamo ndi nyumba zobiriwira. Zovuta za phwetekere ndi mtundu wamtundu wa bowa zimakonda kuchitika mu Marichi. Monga lamulo, kale pa mbande za phwetekere, masamba amayamba kuuma m'mphepete, ndipo ngati mumalimbitsa ndikuchotsa vutoli, mbewu nthawi zambiri zimatha.
Vuto lachiwirili ndi bowa Oidiopsistaurica, zizindikilo zake zakunja zimawoneka ngati mawanga achikasu omwe amakhala kumtunda kwa masamba a phwetekere, koma zokutira zoyera ngati chipale, zofanana ndi ufa wa peyy, zimayamba kuwoneka pansipa.
Kuti muchepetse kufalikira kwa matenda awiriwa oyamba ndi mafangasi, ndikofunikira kunyowetsa nthangala za phwetekere musanafesere kwa masiku angapo mu yankho la "Epina" kapena "Heteroauxin", "Zircon" ndi kukonzekera kwofananako, komwe kumapangitsa kukula komanso kulimbitsa chitetezo cha mbewu.
Koma bwanji ngati kachilombo ka phwetekere kena kale? Njira yoyamba ndiyo kuchitira mbewu zonse za phwetekere, zonse zathanzi komanso zodwala, pogwiritsa ntchito sodium humate. Mankhwalawa amathandizira kuletsa, mpaka kuima kwathunthu, kukula kwa conidia - causative wothandizila wa matenda, chifukwa chake, akuletsa kukula kwa matenda omwewo.
Kukonza kuyenera kuchitika motsatira malangizo omwe ali phukusili, gwiritsani ntchito mlingo moyenera ndikuwongoleredwa ndi nthawi yomwe mukukonzedwa. Kuphatikiza apo, pamagawo oyamba opezeka ndi matenda oyamba ndi fungus, othandizira atha kuthana ndi chiwonongeko cha powdery mildew, osachepera njira yodziwika bwino "Bactofit", yomwe imagwiritsidwa ntchito kupopera mbewu za phwetekere katatu sabata iliyonse, mwachilengedwe, zizindikiro za powdery zikadzawoneka. .
Malinga ndi olimiwo, madzi omwe amatchedwa "Plriz" amatulutsa bwino, koma ndi othandiza pazizindikiro zoyambirira za matendawa, kotero mbeu za phwetekere zikufunika kuyang'aniridwa mosamala kuti zizindikire izi.
Ngati mbewuzo zili ndi kachilombo kale, ndiye kuti muyenera kugwiritsa ntchito fungicides zovomerezeka (zopezekanso - motsatira malangizo omwe ali phukusi). Zitha kukhala mankhwala monga "Strobi", "Topaz", "Quadrice", "Titovit Jet", "Bayleton" komanso "Privent". Wamaluwa amalangizira, makamaka pazaka zonyowa, pamene ufa wa powdery akukwiya, kotero kuti mankhwalawa amakhalanso nthawi yayitali pazomera, kuwonjezera sopo wochapira (nthawi zambiri kapu imodzi ya 10 l) yankho.
Ndi kugonjetsedwa pang'ono kwa mbewu za phwetekere ndi powdery mildew, ndizotheka kuti musagwiritse ntchito umagwirira. Omwe ali m'munda amawona kuti chithandizo chokhala ndi mkaka 10% wamkaka umapereka zotsatira zabwino, zothandizira kupewa, pakakhala kuti ndi kofunda, koma phokoso la powdery silinawonekere, komanso kwa omwe ali ndi mankhwala pomwe masamba ochepa adakhudzidwa, koma ndichomveka kuwachotsa.
Chachikulu ndikuti, mukalandira chithandizo chamankhwala a mkaka Whey sichimavumba, apo ayi chilichonse chidzayenera kuchitika mwatsopano. Ena amazindikira kugwira bwino ntchito kwake polimbana ndi ufa wa phula ndi phulusa, chifukwa cha izi, phulusa lamatanda pafupifupi 100 limathiridwa pa lita imodzi yamadzi ndipo mbewu zopatsidwazo zimathiriridwa ndi voliyumu iyi, ndikugwiritsa ntchito yankho lake kuti ifike pamagawo omwe ali ndi kachilombo. Poterepa, mutha kuchulukitsa pafupipafupi kumasula nthaka ndikuchepetsa kuthirira kwa nthaka.
